LT5525

High Linearity, Low Power

Downconverting Mixer

FEATURES

DESCRIPTIO

The LT^®5525 is a low power broadband mixer optimized

for high linearity applications such as point-to-point data

transmission,highperformanceradiosandwirelessinfra-

structure systems. The device includes an internally 50Ω

matched high speed LO amplifier driving a double-bal-

anced active mixer core. An integrated RF buffer amplifier

providesexcellentLO-RFisolation.TheRFinputbalunand

all associated 50Ω matching components are integrated.

The IF ports can be easily matched across a broad range

of frequencies for use in a wide variety of applications.

■

Wide Input Frequency Range: 0.8GHz to 2.5GHz*

■

Broadband LO and IF Operation

■

High Input IP3: +17.6dBm at 1900MHz

■

Typical Conversion Gain: –1.9dB at 1900MHz

■

High LO-RF and LO-IF Isolation

■

SSB Noise Figure: 15.1dB at 1900MHz

■

Single-Ended 50Ω RF and LO Interface

■

Integrated LO Buffer: –5dBm Drive Level

■

Low Supply Current: 28mA Typ

Enable Function

Single 5V Supply

■

The LT5525 offers a high performance alternative to

passive mixers. Unlike passive mixers, which require high

LO drive levels, the LT5525 operates at significantly lower

LO input levels and is much less sensitive to LO power

level variations.
